Abstract: An impact mill using hammers to strike particles and reduce their size as the material progresses through a grinding chamber. Baffles are provided in the grinding chamber, adjacent the interior wall thereof, concentrically about the drive shaft of the mill. The baffles are adjacent to the hammers in the area of hammer sweep and form a path for the material using the flow of air through the mill and the swing of hammers to keep material from falling within the mill and remaining in the hammer sweep area. A variable speed motor varies the rate of movement of the hammers to increase or decrease the rate of strike of hammers to more efficiently and effectively reduce the material passing therethrough. The baffles can be retrofit into existing mills and can be created in angular sections with the lining of the grinding chamber for modular installation and removal.

Abstract: A method for detecting frequency mismatch in microelectromechanical systems (MEMS) gyroscopes is described. Detection of the frequency mismatch between a drive signal and a sense signal may be performed by generating an output signal whose spectrum reflects the physical characteristics of the gyroscope, and using the output signal to determine the frequency fC of the sense signal. The output signal may be generated by cross-correlating a random or pseudo-random noise signal with a response signal, where the response signal can be obtained by allowing the noise signal to pass through a system designed to have a noise transfer function that mimics the frequency response of the gyroscope. Since the noise signal is random or pseudo-random, cross-correlating the noise signal with the response signal reveals spectral characteristics of the gyroscope. To improve computational efficiency, the cross-correlation can be performed on demodulated versions of the noise signal and the response signal.

Abstract: A shape of a transmitted LIDAR pulse can be measured contemporaneously with operation of the LIDAR system, such as to account for variations in the shape of the LIDAR pulse, such as due to changes in environmental or operation conditions. The measured shape can then be used to determine an arrival time of LIDAR pulses received from a target region with improved accuracy.

Abstract: Systems and techniques are described for matching the resonance frequencies of multiple resonators. In some embodiments, a resonator generates an output signal reflecting the resonator's response to an input drive signal and an input noise signal. The output signal is then compared to the noise signal to derive a signal representative of the resonance frequency of the resonator. Comparing that signal to the output signal of a second resonator gives an indication of whether there is a difference between the resonance frequencies of the two resonators. If there is, one or both of the resonators may be adjusted. In this manner, the resonance frequencies of resonators may be matched during normal operation of the resonators.

Abstract: A system and method provide for an adaptive median filter with edge protection and four line buffers to remove the impulse noise for a Bayer pattern image. The system and method separates the Bayer pattern image data into different channels by color and applies the adaptive median filter to remove the impulse noise on each channel. The adaptive median filter has five threshold values that may be modified to achieve different light condition response based on the detected noise level of the image. Thus, proper threshold values with better brightness response to the input pixels may be applied and impulse noise may be suppressed effectively, while preserving image details.
